| 摘 要： | 本文研究Sankar提出的,用全位势方程求解跨音流场的强隐式方法(Strongly Implicit Procedure)。针对强隐式方法在求解跨音流场中的问题作改进,即采用了新的人工压缩密度计算方法,计算绕孤立机翼、叶栅通道的跨音流场,降低了在跨音位流计算中激波前后的数值振荡,并提高了算法的稳定性,

| Abstract: | A modified Strongly Implicit Procedure for transonic potential flows is studied in this paper.In the method,a new technique of the artificial density calculation is used for eliminating the large pre-shock oscillations in flow field.Transonic airfoil and cascade flows are simulated numerically.The effect of the mesh and the coefficient in the artificial density are discussed. ; |
